Make sure the firmware entry is uncommented and let the file-path point to where you put the firmware file for your scanner. Be sure that members of the group Template:Codeline can access the Template:Filename file.

If the backend of your scanner is not part of the sane package (such as hpaio.conf which is part of hplip), you need to uncomment the relevant entry in /etc/sane.d/dll.d/hplip.

Step 5: Install some frontend(s)

XSane provides a GTK-based frontend to Sane. It is available in the Template:Codeline repository.
